Product Description

Yudian Make Industrial Multi Loop Controller AI-7048

We are counted among the most reliable manufacturers, supplier and exporters of Multi Loop Controller. These controllers are used for measuring as well as controlling four different channels of temperature with individually definable input specifications for every channel. Moreover, these controllers are compatible with programmable logic controller and with computer too. Our offered Multi Loop Controller is capable of working independently and that too with high efficiency and operational accuracy.

Industrial Multi Loop Controller:

AI-7048 is capable of measuring and controlling four channels of temperature, and every channel can define its own input specification. AI-7048 can either work independently or cooperate with computer or PLC (Programmable Logic Controller).

 Its Features:

  • Providing up to four channels of configurable inputs, and supporting multiple thermocouple inputs with auto reference junction compensation and linear voltage inputs with user defined scale. Every channel has its own digital filtering and can adjust its filtering degree.
  • High performance hardware design, which greatly decreased temperature drift and the interference among the four channels. Therefore, this multi-channel instrument obtains the same measurement accuracy and anti-interference ability as that of single channel instrument.
  • Every channel has independent high/low alarms, and the alarms can be allocated to different alarm outputs or to the same alarm output.
  • Friendly and customized operating interface leads to easy learning and simple manipulation. Up to 12 parameters can be promoted to immediate operator access in Field Parameter Table.
  • Advanced communication functions, compatible with the communication protocol of other AI series instruments. One AI-7048 communicates with the host computer the same as four independent controllers.
  • Universal power supply of 100-240VAC or 24VDC.
  • New generation D5/E5 rail mounted dimension. The width of D5 is only 22.5mm. The instrument can be easily configured by connecting to handset display.
  • ISO9001 and CE certified and satisfied with EMC standard, achieving world class level of quality, anti-interference ability and safety. The power and all I/O terminals passed 4KV/5KHz EFT test, and the instrument can work stably under interference.
  • Over range and sensor fail  output off, Auto Tuning, Input Offset.
